Given that,

Length of a solenoid, l = 1.5 m

Diameter of solenoid, d = 4 cm

Radius, r = 2 cm

Number of tunrs per unit length is,N=\dfrac{n}{l}=\dfrac{10}{cm}=1000\ \text{turns}/\text{m}

Current, I = 5 A

To find,

The magnetic induction inside the solenoid.

Solution,

We know that,  the magnetic induction at the axis inside the solenoid is given by :

N=\mu_o NI

B=4\pi \times 10^{-7}\times 1000\times 5\\\\B=2\pi \times 10^{-3}\ T

So, the magnetic field inside the solenoid is 2\pi \times 10^{-3}\ T.
